Respiratory System Anatomy

Front

Pharynx

Back

The throat, a muscular tube that connects the nasal cavity and mouth to the esophagus and larynx.

Front

Lungs

Back

The site of gas exchange in the respiratory system, where oxygen is absorbed and carbon dioxide is expelled.

Front

Nasal Cavity

Back

Hollow space area behind the nose that filters, warms, and moistens air before it enters the lungs.

Front

Bronchi

Back

Main passageway into the lungs, branching from the trachea and leading to each lung.

Front

Bronchioles

Back

Small air passages that transport air to the alveoli, where gas exchange occurs.

Front

Alveoli

Back

Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

Front

Trachea

Back

The windpipe; a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

Diaphragm

Back

A dome-shaped muscle that separates the thoracic cavity from the abdominal cavity and plays a crucial role in breathing.

Front

Gas Exchange

Back

The process of oxygen entering the blood and carbon dioxide being removed, occurring in the alveoli.

Front

Respiratory System

Back

The system responsible for the intake of oxygen and the expulsion of carbon dioxide, consisting of the lungs, trachea, bronchi, and other structures.
